PATIENT EDUCATION

ENDODONTIC SURGERY

Our team of dental specialists and staff strive to improve the overall health of our patients by focusing on preventing, diagnosing and treating conditions associated with your teeth and gums. Please use our dental library to learn more about dental problems and treatments available. If you have questions or need to schedule an appointment, contact us.

In some cases, your root canals are unusually narrow or blocked (sometimes by calcium deposits or other debris), making a repeated root canal procedure ineffective. In other cases, a root canal procedure may fail or an infection recurs after a long period of time. In these cases, endodontic surgery may be needed and is the only alternative to tooth extraction.

Endodontic surgery is usually called for under the following circumstances:

Acute pain.

Diagnosis of canals and inner tooth structures that cannot be performed non-surgically.

Conventionally blocked root tips.

Cracked roots.

Perforated root tips.

Persistent cysts.

Removal of a debris from a previous root canal that could damage root tips if left inside the tooth.

Unusually formed molars, incisors, and first premolars, which often have complex and tiny canal divisions that cannot be treated with conventional endodontic treatment.

The most common types of endodontic surgical procedures are apicoectomy, intentional replantation, hemisection, and retrosealing. Here's a brief look at those procedures: ApicoectomyIn some cases, surgery is required to closely examine the tiny canals that are not visible to the naked eye. Only through such procedures can an accurate diagnosis be made. The most common non-diagnostic endodontic surgical procedure is an apicoectomy, or root-end resection.

An apicoectomy is often performed when inflammation or infection persists in the bony area around the end of your tooth after a root canal procedure.

An apicoectomy often involves removal of the end of the root of the tooth. During the procedure, the gingival (or gum) tissue near the tooth is opened with an incision. This allows the underlying bone to be examined and inflamed or infected tissue to be removed.

Afterwards, a small filling may be placed to seal the end of the root canal, and a few stitches or sutures are placed in the gum tissue to aid healing.

Intentional replantation

Intentional replantation involves extracting the affected tooth, repairing the tooth endodontically outside the mouth, and re-inserting, or re-planting, the tooth in its socket.

HemisectionHemisection is a surgical procedure in which a single root of a multi-rooted tooth is removed because it cannot be repaired or treated, or bone loss around an individual root (usually as a result of periodontal disease) makes conventional endodontic treatment impractical. Hemisection is usually a procedure called for as a last resort before extraction.

In other cases, the front root of a lower second molar may be removed and used as a bridge anchor to replace a missing first molar, thus preventing the need for a partial denture or dental implant.

RetrosealRetrosealing is often performed to re-seal the canals following an apicoectomy. Retroseal is the process that finally resolves most endodontic failures.
